5f08b9ade4 build: Remove redundant comparisons 
If a Meson option is typed as `boolean`, the `get_option` returns a
boolean, and comparing it with `true` is redundant. Meson also errors if
you try to compare across types, so it couldn't _not_ be a boolean.

Also, Meson is not C, so no need for parentheses around `if` conditions.

9c36b78140 lottie: ensure a null terminator at the end of the copied data 
In certain cases, the user might want to set mapped memory directly.
This update ensures that a null terminator is appended to the string data.

e50bf002de lottie: handle edge case for rounded rect 
For rounded rectangles the roundness value should
be determined using to the formula:
r = min(r, max(size.x, size.y)/2)
rather than the previous method:
r = min(size.x/2, size.y/2, r)

ttf_loader: Basic support for composite glyphs loading (#2600) 
Adds the ability to load some composite glyphs and prevents an error when a composite glyph is used.

Implementation based on ttf glyf table documentation: https://learn.microsoft.com/en-us/typography/opentype/spec/glyf

There are still some missing features like scaling, parent glyph point based positioning etc. I think this is a topic for future work. Howerever, it looks like implemented features are enough for utf-8 latin subset in major fonts.

issue: #2599
